MetaMask is a popular cryptocurrency wallet available as both a mobile application and a browser extension. It serves as a gateway to blockchain applications and decentralized finance (DeFi) platforms. While originally designed for the Ethereum network, MetaMask now supports various other blockchain networks, including the BNB Smart Chain (BSC).
The BNB Smart Chain hosts over 900,000 active addresses and supports smart contracts and decentralized applications. Adding it to your MetaMask wallet expands your access to a vibrant ecosystem of DeFi protocols, gaming platforms, and other utilities. This guide provides a clear, step-by-step process to integrate BSC into your MetaMask setup.
Can You Add BNB Smart Chain to MetaMask?
Yes, you can add BNB Smart Chain to MetaMask. Since BSC is EVM-compatible—meaning it supports the Ethereum Virtual Machine—it integrates seamlessly with MetaMask. This compatibility allows users to interact with BSC-based decentralized applications directly through their MetaMask interface.
Understanding the BNB Smart Chain
The BNB Smart Chain is a blockchain network launched by the cryptocurrency exchange Binance. It originated as a hard fork of the Go Ethereum (Geth) protocol, which is one of the original implementations of the Ethereum network. Built using the Go programming language, BSC supports smart contracts and decentralized applications.
A key differentiator of BSC is its consensus mechanism. Instead of using Proof of Work (PoW) like Ethereum originally did, BSC employs Proof of Staked Authority (PoSA). This mechanism enables faster block times—approximately three seconds per block—and significantly lower transaction costs compared to Ethereum.
The native token of the BNB Smart Chain is BNB. This token is used for paying transaction fees, participating in staking activities, and compensating network validators. With over $5 billion in total value locked, BSC ranks among the top blockchain networks in the DeFi space. The network hosts hundreds of decentralized applications spanning various categories including decentralized exchanges, gaming platforms, and real-world asset projects.
How to Add BNB Smart Chain to MetaMask Manually
The manual method of adding BSC to MetaMask involves entering network parameters directly into your wallet. This approach gives you full control over the process and helps you verify the authenticity of the network details.
Required Network Parameters
To add BNB Smart Chain manually, you will need the following details:
- Network Name: BNB Smart Chain
- Chain ID: 56
- Currency Symbol: BNB
- Block Explorer URL: https://bscscan.com
These parameters ensure your wallet connects to the main BNB Smart Chain network rather than a testnet or fraudulent copy.
Step-by-Step Implementation
- Open your MetaMask extension and click on the network selection dropdown at the top of the interface
- Select "Add network" from the bottom of the dropdown menu
- Click on "Add a network manually" to access the input fields
- Enter the network parameters listed above in their respective fields
- Click "Save" to add BNB Smart Chain to your available networks
After completing these steps, you can switch to BSC by selecting it from your network dropdown menu. Remember that you'll need BNB tokens in your wallet to perform any transactions on the network.
How to Add BNB Smart Chain to MetaMask Automatically
For users who prefer a more streamlined approach, MetaMask offers an automatic method to add compatible networks. This process eliminates the need for manual data entry and reduces the risk of input errors.
The automatic addition method typically involves interacting with a decentralized application that supports network integration. Many BSC-based platforms offer a "Connect to BSC" or similar button that automatically configures your MetaMask wallet when authorized.

When using automatic addition methods, always ensure you're interacting with reputable platforms. While convenient, this approach requires trust in the application providing the network configuration.
Benefits of Using BNB Smart Chain with MetaMask
Integrating BSC with your MetaMask wallet unlocks several advantages:
Cost Efficiency: Transaction fees on BSC are significantly lower than on Ethereum, making it more accessible for regular users and small-scale transactions.
Speed: With its three-second block time, BSC processes transactions much faster than many other blockchain networks.
Ecosystem Access: Gain entry to hundreds of decentralized applications including popular DeFi protocols, play-to-earn games, and innovative Web3 projects.
Cross-Chain Compatibility: Since BSC is EVM-compatible, many skills and concepts from Ethereum directly transfer to the BSC ecosystem.
Security Considerations When Adding Networks
While adding custom networks to MetaMask is generally safe, following security best practices is essential:
- Always verify network details from official sources before adding them to your wallet
- Be cautious of unsolicited requests to add new networks
- Regularly update your MetaMask extension to benefit from the latest security enhancements
- Consider using a dedicated wallet for experimenting with new networks rather than your primary wallet
Frequently Asked Questions
Why should I add BNB Smart Chain to my MetaMask wallet?
Adding BSC to MetaMask enables interaction with hundreds of decentralized applications while benefiting from lower transaction fees and faster processing times compared to Ethereum. It's essential for anyone exploring the BSC ecosystem.
Do I need BNB tokens to use the BNB Smart Chain?
Yes, you need BNB tokens to pay for transaction fees on the network. These tokens are also used for staking and participating in network governance through various platforms.
Is it safe to add custom networks like BSC to MetaMask?
Adding custom networks is safe when using verified parameters from official sources. Always double-check network details against reputable documentation to avoid connecting to malicious networks.
Can I use the same MetaMask wallet for both Ethereum and BSC?
Yes, the same MetaMask wallet can manage assets on both Ethereum and BSC. Your wallet address remains the same across all EVM-compatible networks, and you can easily switch between networks using the dropdown menu.
How do I switch between different networks in MetaMask?
Click on the network selection dropdown at the top of your MetaMask interface and select your desired network from the list. Recently added networks will appear here for easy access.
Can I remove BNB Smart Chain from MetaMask if I no longer need it?
Yes, you can remove any custom network by navigating to Settings > Networks, selecting the network you want to remove, and clicking the "Delete" button. This action doesn't affect your assets but merely removes the network configuration from your wallet.
